STICKER ROD.

Application led June 30,

This invention aims to provide a coupling 'for sucker rods or the like,embodying .interiitting sections designed to be quickly and convenientlyassei'nbled or disassembled as the occasion may require, without the useof wrenches or other tools, together with means for holding the sectionslined relatively when assembled.

The nature and adwrntages of the invention will be better understoodwhen the tolllowing detail description is read in comico" tion with theaccompanying drawing, the invention residing .in the construction,combination and arrangement of parts claimed.

In the drawing forming part of this applition like numerals of referenceindicate similar parts in the several views and wherein:

Figure 1 is a perspective view of one of the sections.

Figure 2 is a similar view of the other section.

Figure 3 is a view partly in section showing the sections assembled.

Referring to the drawing in detail A and i3 represent the respectivesections of the coupling, the upper and lower end portions of therespective sections being' lindicated at 10 and 11, and each having;lits opposed sides lattened. as at The section A includes a shank 13 Jromthe opposite sides of which project lugs arranged in pairs, one pair oflugs being indicated at 1% and spaced 'from the other pair of lugs 15.One side of the shank 13 is also provided with a resilient hook-likelatch 16 Jfor a purpose to be hereinafter described.

The section B is hollow to receive the shank 13, the lower portion ofwhich shank and lugs 15 being adapted to repose upon the end portion 11of the section B. Thesection B is provided with spaced pairs ofcurvedlugs 1T, and lwhen the shank 13 is received by the section B, thelugs carried by said shank are arranged between the lugs 17 as clearlyillustrated in the drawinof. The section B is 1927. Serial No. 202,661.

provided with a shoulder 18 having secured thereto a metallic wear plate19, adapted to be engaged by the hook-like latch 16 when the sectionsare assembled as shown in Figure 3. The end portion 'l1 or the section Bis also provided with a slot QOadapted to receive a sliding latch 21carried by the section A to assist in holding the sections assembled. Itis manifest, that by reason of the construction shown and described, thecomplementary sections oi the coupling can be very easily and quicklyassembled or disassembled without the use ot any tools for this purpose.

Vilhile it is believed that from the foregoing description, the natureand advantages of the invention will be readily apparent, we desire tohave it understood, that we do not limit ourselves to what is hereinshown and described and that such changes may be ref sorted to whendesired as fall within the scope of what is claimed.

What is claimed is:

A coupling of the character described comprising two complementarysections, one section including a reduced shank of rectangular contourin cross section, lugs projecting from the opposite sides of the shankand arranged in pairs, with one pair disposed above the other, the othersection being hollow rcceiving the shank, spaced upper and lower pairsoil. curved lugs projecting from the longitudinal. edges oit' the secondmentioned section and fitted between the lugs on said shank, said secondmentioned section having a transverse opening arranged between its pairsof lugs and providing an upstanding shoulder, and a resilient hookcarried by the longitudinal side of said shank and projecting throughthe opening and overlying the shoulder.

.ln testimony whereof we al'lix our signatures.
